In short, there were a bunch of errors committed here. Trying to
cheaply fix up a laptop that was worth nothing anyway, getting cheap
and buying off eBay from China, accepting whatever junk they sent.
Get the correct battery, or junk the notebook (best move) and have a
beer. Forget the Chinese seller, and eBay the battery they sold you
and maybe you will recover *some* of the money you wasted.
Thanks for the advice. Unfortunately my friend is chronically ill, and is
on an extremely tight budget. So while you or I might have junked the old
machine and forked out £400 for a much superior model, she is not able to.
She also felt that spending over £100 on a new battery was just not possible
at present.

I've never heard of an 11.1 V battery - something is wrong here.
Lithium cells have about 3.7 volts per cell. 3 cells is 11.1 volts.
4 cells is 14.8 volts.
